FormSpring is a handy service that allows you to build online forms. You can either host it on your site or let FormSpring host it (for free).

It’s great for contact forms, event registrations, feedback, job applications, surveys and sign-up forms for newsletters. With the free version, you can create 3 forms with up to 15 fields each. The next level starts at $9 a month for 5 forms with 30 fields.

Super cool … nonprofits get a 10% discount.
